I’m going through the course for the first time and in chapter 4 it states that the following are equivalent:
- (a_3 - mean7).abs().mean()
However when using the F.l1_loss to calculate distance in the broadcasting example the function fails. Why?
I had a look at the doc for both abs and F.l1_loss but they aren’t very helpful
But judging from the error it looks like the l1_loss isn’t capable of broadcasting?
TIA for any answers, thoughts, or other lines of investigation.
